"UNTTEE STATES PATENT HARRY L. HESS, OF ASHLAND, OHIO, ASSIGNOR TO THE OOLUMBIAN HARDWARE COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

CHECK FOR SWING-DOORS.

To all whom it may concern:

Be it known that I, HARRY L. Hess, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Checks for Swing-Doors, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to checks for swinging-doors, and the object of the invention is to provide a checking or retarding mechanism adapted to be set into a door, and

frame therefor and to serve as a striking medium for a door of the kind adapted to swing through the frame back and forth to either side as in double hinged swinging doors generally. In such doors as they are ordinarily mounted there is no checking or stopping of the door as it swings forcibly to what would otherwise be closing position, but the door is permitted to swing freely through to the opposite side, and it usually depends upon the distance the door is opened,

or other conditions as to how far it will swing past the closing point or jamb to the opposite side and then play back and forth for a time before it actually settles down to rest.

My invention is designed to provide a summary check for the door on its firstreturn movement, so that as it swings to close it will stop at the jamb and not pass through, but the checking mechanism is of such a character that it clears itself of obstruction the next moment and the door is permitted to settle down to normal position as before.

To these several ends the invention con sists in a check for swinging doors constructed and adapted to operate substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a cross section of a swinging door and the frame therefor containing my improved stop mechanism. Fig. 2 is an enlarged elevation of the checking mechanism alone and apart from its supports. Fig. 3 is a cross section of the jamb showing the auxiliary stop.

As thus shown A represents the door frame, which may be of the usual kind, and B is the door, supported on double hingesb, as usual, whereby the door is free to swing Specification of Letters Patent.

oppositely through the frame or opening for the door as in oppositely swinging doors usually.

The principal elements of the checking mechanism are shown in this instance as located in the jamb of the door but they might be in the door itself, and comprise a metallic casing or shell C, which contains the other parts and which comprise an angle member or right angled arm G, a striking roller or abutment-portion H connected with said member, and a dog or latch L pivoted on said member and adapted under certain conditions to strike a shoulder or stop 2 in said casing and for the moment arrest the retirement of said parts and thus bar the further passage of the door for the time being.

The roller or abutmentportion H has a possible outward movement in front of the door frame or jamb relatively about as shown in Fig. 2, so that it thus comes di rectly in the path of the door when the door has been pushed open past the same, but is designed to rest opposite the door and to be pressed inward from its striking position, Fig. 2, when the door has closed itself in the usual manner, Fig. 1. The roller or abutment-portion H is carried by a support J, providing a movable interfering, or actuated, member which is adapted to slide back and forth in casing C and is pivotally connected to the arm 3 of the free swinging member G. The rearward or inward thrust of roller H comes directly upon this member, which is caused to fall back and operate as will now be seen. Thus, as against this rearward thrust and the movement of angle member G on its pivot is tension spring 5 engaged with arm 4: of said memberat one end and with the casing at the other and adapted to counteract said effect yieldingly but yet with a due measure of resistance. This spring furthermore is strong enough to throw the roller or abutment-portion H outward when resistance is relieved therefrom. Now, as a further modification in the action of roller or abutment-portion H it will be noticed that there is a dog, pawl, or latch L, pivoted on the arm 3 of angle member G at 7 and alongside of pivot point 8 of roller support J thereon. This part L is adapted under certain conditions to strike stop 2, and under other conditions to avoid or pass said stop, and is normally held in fixed position full lines, Fig. 2, so as to avoid stop 2 by means of a spring mechanism 9, engaged at one end to a short arm 10 on said part away from its pivot 7, and at the other end to member G near its pivot, but it might be attached to casing G as well. The long arm of the latch L, as shown in Fig. 2, normally bears against an extension 3 upon the member G. It will be understood that in use the support J is held in its inner position by the door and is released and thrown out to set the latch L, in operative position when the door is opened.

It follows with this construction and arrangement of parts that when the door has been opened, say the usual distance for passing through, it will, when released, swing back also as usual and with considerable violence or force. As it does this the striking device N on the door impacts with its beveled edge against or upon roller or abutmentportion H and drives it suddenly backward, say to position dotted lines Fig. 2 and causes the spring 9 to lose control of the latch. As this occurs the inertia and weight of latch L is such that for the moment it is retarded at its engaging point while its pivot is being carried rearward, and thus it engages stop 2 before spring 9 can assert its control thereof. The result is that roller or abutmentportion H is checked from making a full retreat and the door is stopped. From. this short sudden pause the door naturally rebounds, dotted lines Fig. 1, and in doing this spring 5 takes control of the parts and restores them quickly to full lines. Then as the door again strikes the roller or abutment-portion its movement is so easy that said spring and spring mech anism 9 can hold the dog or latch L away from engagement with stop 2, and so it occurs that the door will assume its position of rest without further hindrance and with much more prompt-ness than formerly.

The striking device N has a reversely beveled head and a stem supported in a suitable socket in the door, and may be made of any suitable material which will avoid noise, as also is the roller or abutment-portion H. In some instances it may be desirable to mount the roller or abutment-portion in the door and said striking device in the door jamb.

The roller support J is provided with shoulders or lugs 12 to prevent it from moving outward beyond certain point.

A set of auxiliary spring pressed stops K are also mounted on the door casing A in the path of door B, and the door is adapted to rest be held centrally within the stops as against wind pressure or drafts but these stops K may be omitted as they are not essential to the operation of the device.

hat I claim is 1. A check for swinging doors, comprising a movable interfering or actuated member, means for projecting the said member so as to be struck by a door, and arresting means connected with the movable interfering or actuated member adapted independently of the resisting action of said projecting means to momentarily retard the movement of said movable interfering or actuated member in its initial action.

2. A door-check, comprising a movable interfering or actuated member adapted to move to and fro, means for projecting the said member so as to be struck by a door, and arresting mechanism connected with the movable interfering or actuated member adapted independently of the resisting action of said projecting means to retard the initial movement of said movable interfering or actuated member when said movable interfering or actuated member is forcibly engaged, said arresting mechanism having no action on the interfering or actuated member when the check is at rest.

3. In a door-check, a movable interfering or actuated member provided with a striking roller or abutment portion, a pivoted spring arm with which said member is pivotally connected, a latch pivotally engaged with said arm, and astop adapted to be engaged by said latch when the latch is caused to change its normal position.

t. The combination of a door and a frame therefor with a door-check mounted on one of said parts and a beveled striking member mounted upon the other part, and a latch for said door-check arranged to hold the check in the path of the door in swinging and to hold the door stationary only when said check is forcibly engaged by said beveled member, said latch having no effect on the door when the latter is in closed position of rest. I

5. The combination of a double swinging door and a frame therefor, with a movable interfering or actuated member held in its inner position by the door, means for throwing out the movable interfering or actuated member when the door is opened and door stops mounted on said frame for holding the door in position against the movable interfering or actuated member until the door is opened and comprising a spring pressed stop at each side of said door and adapted to be engaged by the edge of the door.

6. In a door-check, the combination of a movable interfering or actuated member, and suitable means operated by the movable interfeing or actuated member to momentarily block and interrupt the movement of said member at a point between its limits of movement and before the door can come to its position of rest, said parts being combined as one organized mechanism apart from any striking member.

7. In a door-check, the combinationof a movable interfering or actuated member, a latch adapted to be thrown by a sudden shock on the movable interfering or actuated member, and a stop to engage the latch when so thrown, said parts being combined as one organized mechanism apart from any striking member.

8. In a door-check, the combination of a movable interfering or actuated member, a movable arm acted on by said movable interfering or actuated member, a latch acted on by said arm, and a stop for the latch, said parts being combined as one organized lechanism apart from any striking member.

9. In a door-check, the combination of a movable interfering or actuated member, a movable arm acted on by said movable interfering or actuated member, a latch acted on by said arm, a stop for the latch, and springs acting separately on the arm and latch, said parts being combined as one organized mechanism apart from any striking member.

In testimony whereof I sign this specification in the presence of two witnesses.
